METHOD OF DISMANTLING OF DAMAGED BEAM OF BRIDGE SPAN Russian patent published in 2015 - IPC E01D24/00 

FIELD: construction.

SUBSTANCE: damaged beam is cut into separate elements of a beam, then the bearing spreader bars are mounted, with their supporting through bearing elements on two neighbouring beams, then subspreader bars are mounted, slinging holes are drilled in a horizontal plate of the damaged beam, then with rods through slinging holes the bearing spreader bars are combined with the beam elements and subspreader bars, after that rods a re pulled and the beam elements are lifted, then beam elements are transported to the spreader bar dismantle after that spreader bars are dismantled and beam elements are transported to the utilisation place. Cutting of the damaged beam into separate elements of the beam is performed by the diamond tool. All works are performed locally, without disturbing operations of the site unaffected by repair. The place of mounting of bearing spreader bars and subspreader bars per each beam element is determined by calculations. Beam elements a re lifted by cranes with the respective loading capacity.

EFFECT: lower costs.
